Arsh copperbond earth rods probably offer to the installer the best and most economical earth rods available. They are made by molecularly bonding 99.9% pure electrolytic copper onto a low carbon steel core.
Arsh rods are not of the sheathed type. They are highly resistant to corrosion, and because the steel used has a very high tensile strength, they can be driven by power hammers to great depths.
The counter-bored couplings are made from high copper content alloy, commercial brass is not used. This again ensures excellent corrosion resistance and high strength.
Copper thickness minimum 250 microns.
